Overview

The LMV339IPWR is a quad-channel, low-voltage comparator designed for cost-sensitive applications requiring multiple comparison stages in a small footprint. It features an open-collector output, allowing for level shifting and wire-OR connections, and operates with a wide temperature range of -40 to 125 degrees Celsius. This general-purpose component is optimized for 2.7V to 5V systems where low quiescent current and space efficiency are primary design goals.

Why Choose This Part

The quad-channel configuration provides high integration in a 14-TSSOP package, reducing PCB area compared to multiple single or dual packages. Its open-collector output offers significant flexibility for mixed-voltage logic and wired-OR logic configurations, while the 100uA per channel quiescent current minimizes power budget impact.

Applications

Battery Voltage Monitoring
Utilizing the low power consumption and ground-sensing input range to trigger low-battery alerts in cordless tools and appliances.
Level Shifting
Using the open-collector output to interface 3V logic signals with higher voltage 5V subsystems.
Oscillator Circuits
Configuring the four elements for clock generation and square wave output in server power supply control units.
Sensor Threshold Detection
Implementing window comparators for vacuum robot collision sensors or home appliance safety interlocks.

Getting Started

To evaluate this part, use a TSSOP-14 to DIP adapter on a standard breadboard and ensure a pull-up resistor is connected to the open-collector output for proper logic swing. Decouple the supply pin with a 0.1uF ceramic capacitor placed close to the device to minimize switching noise in the comparator outputs.
